To all whom t "may concern.'

Be it known that l, Visco V. TonenNsnN, a citizen of the United States,and a resilen't ci: Cleveland, in the county of Cuya- 1 boga and Stateof Ohio, have invented certain new and useitul Improvements in DrivingMechanism for Motor-Vehicles, ot which the 'followingv is aspeciication.

This invention relates to driving mechanism for motor vehicles, and itis especially useiful in heavier types of motor vehicles, such `astrucks, utilizing internal gear drive.

internal gear drive trucks, as is Well 1iov/n have the ring; gear andone or more .inions at the Wheel inclosed in a casing or ousing toretain the grease and protect the :from dirt. Heretofore, in machineshaving this Construction, if anything should go wrong' With thedifferential gearing or the ack shafts, neither could he taken down forrepairs or replacement 'Without removing the tread Wheels.; and in heavytruclrs7 particularly those using steel Wheels, the wheels are so heavythat they cannot loe handled on the road or Without special apparatus.lt is, therefore, important to provide ttor the removal or displacementof the driving` shaits and for the removal of the diiiorential gearing'Without having` to remove the tread Wheels; and this is one of theobjects of my invention. n

i-inether object oi' the invention is to provide simple and eicientmeans for this purpose7 permitting the jack shafts to loe displacedend\vise after which the differential gearing 'may vhe removed. I

Another object of the invention is the maintenance or' the mesh of thedriving pinion atthe Wheel with its acent gear when the drivingshaft isdisplaced or removed.

My invention consists in the novel ifeatures and combinations of partshereinain-,ter descriloer in their preferred tornn and the invention ismore particularly pointed out in the appended claims.

1Eurther objects and advantages of the invention and features ot.improvement Will more tulljv appear from the following detalren inconnection With the accompanyingI drawings, in which Tfigure l is a planvieu' largely in horizontal section of a driving apparatus einhodyingniyinvention in a preferred forni, Fig. 2 is a similar lout enlarged viewof a portion ot the appa- Speciiieaton of Letters Eatent.

he hralre drum member is rigidly secured to the web 5 oi the Wheelstructure by bolts i2, and the Wheel structure is provided with aperipheral tread riin 13 which in this instance is of steel and formedintegrally with the web. Y

ligidly secured tothe brake drum mem,- her 9 (Fig. l) hy rivets le andforming a part ci' the Wheel structure., is a ring; i4 having `gearteeth l5 ordriving the traetion Wheel structure Meshing with this gearthere is a driving pinion 1G (Figs. l

`:tor journaling the pinion .in the annular y rlilhe jaclr shaft .i8 hasintegral With it at its end, tour radial projections 19 (Fig. 3) which.tit into cut-out parts in the end of the. pinion 16 so that shat't 18is locked with the pinion 16 and vWill drive the same. The sleeve l?carries an inner hearing* ring' 2O (Fig. 2) around which are located"hall hearings 2l andV an outer hearing` ring 22 iitting snugly Within acircular' opening in a spider or plate 23 rigidily secured to the axlestructure oy bolts 2l. The hearing thus serves both as a hearing for theend of the drive shaft" and as a means for supporting the' pinioninoperativek position rlhis sleeve" 1 constitutes an extended huh forthe pinion outer ice when the driving shaft is displaced axially. Theplate 23 also has a central opening' at 25 through which the main axlemember ex- 29 on both sides ofthe hub portion 27 to.

effectively exclude dust and dirt-from the bearings 3 and 4 and toprevent oil from running out of the hub portion. Y Y p The internal gear15 is closed to dust and -dirt on one side by the wheel structure, andon the other side by a plate 30 having a cen-l tral opening at 31 (Figs.2 and 5) through vwhich the hub portion 27 passes and provided with anupturned flange 32. atthe periphery. Secured to the plate 30 is a flatring 33'provided with a concentric upturned flange 34 so as to form agroove with flange 32, which is filled with an oily felt packing 35which extends into an opposing groove i 35 in the wheel structure (inthis linstance formed in the end of the internal gearring) andA forms arunning lubricated joint therewith so that dust and dirt are effectivelyexcluded from the chamber containing the internal gear 15 at this point,as well as from the hub chamber containing the bearings 3 and 4. The twochambers are made independent by reason of the hub portion 27 extendinginto the member 23, and the plate 30 bears against and aids in retainingthe packing` 28 in the circular groove in the member 23so that dust anddirty are excluded from the internal gear chamber at this point. Y

In orderto accommodate the drive shaft 18 and the bearings therefor, theplate 30 `and member 33 are cut away from their pe- 'ripheryl as shownat 36 in Figs. Gand 7, and

in the planeof the plate 30 is inserted a plate 37 having an upturnedflange 38 forrningaV continuation of flange 32, and having a circularopening 39 through which the sleeve 16 passes. vAdjacent the plate 37 isplaced another plate 40 having anupturned flange v41Vcorresponding tothe flange 34 on ring 33 so that a groove is formedV between ltheiianges 38 and 41 which is filled with similar packing forming alubricating running joint with the opposing groove in the internal fgear member 15. The plate 4G also has an opening 42 through which thesleeve 16 passes. AV third plate 43 is bolted to the member 23 by bolts44with the plates 37 and 40 between the plates 43 and member 23, so thatthe plates 37 and a() are securely held in position on the member 23,the plate 40 `overlapping the cutaway edge of the plate 30 so as to holdthe lat-terin place against the member 23. i

A plate 50 (Figs. 1 and 2) isrigidly se` cured between the member 23 andshoulder V51 on the axle, the plate'O being riveted to member 23 byrivets 52, and being cut out to permit of insertion of the axle portion2 and drive shaft 18 therethrough. This plate V 50 substantially closesthe third chamber ocrk cupiedfby lthe emergency brake apparatus, to dustand dirt.

Secured to the plate 50are1two thimbles Y i 53 .containing springs 54(see Fig.v 8 also) which bear against the plate 30 tending. to

.force the periphery of the latter'toward the internal gear'member, sothat packing carried by the plate 30 will bear against the internal gearmember with a spring pressure and thus continueV to maint-aina goodjointas the packing wears, and more positively exclude dust and dirt andprevent oil from getting into the emergency brake chamber.

In order to limit the outward movement of" the spring-pressed 'plateV30when the wheel is removed, I provide bolts 54 threaded into thebottoms of the thimbles 53 and having heads 54 adapted, to be engaged bythe 'plate 50 after it `has been moved out a cer-V (Figs. 2 and 4) isheld firmly up toplate-` 50 and member 23 by means of the bolts 44 4andis provided with packings at 61 Vand 62 to prevent oil running out fromthe bearings 21. v Y portion of the drive shaft 18 and a spring A sleeve63 covers the greater clamping nut 66 clamped onto the sleeve 63 1 holdsthe packing 62 in place. A nut 64 screw-threaded on the jack shaft18-mainV tains the sleeve 17, bearing member 20, pinion 16 and drivelshaft 18, pressed together from longitudinal displacement. A screw cap65 closes an opening in the web of the wheel structure opposite theVdriving shaft Y 18, and on removing thiscover the end of ,the drivingshaft may` be easily reached therethrough.

In assembling, the bearing20 withv the balls 21 and ball raceway 22'ispressed onto the sleeve 17, and the parts so far assembled are thenslipped in place in the mem-y ber 23; then the plates 37, 40 and 43 areslipped loosely over the sleeve 17 and screw bolts 44l arey tightened upto force and se cure in place the whole bearing by means of plate 43.The pinion 16 is then fitted tightly on the sleeve 17 andV thereafterthe pinion, sleeve and bearing ring'20 remain relatively fixed as aunit, functioning as if one piece. All this is done before the treadwheel is slipped onto the axle spindle 2.

meneer The tread wheelmay then be put onto the axle spindle 2 andsecured in place by nuts 6 and 7, after Which the driving shaft or jackshaft 18 is slipped through the opening normally closed by the screw capplate 65, and through the sleeve 17 and so that the teeth 19 thereon tin the cutaiay portions in the end Aof the pinion 16 so as to drive thelatter. The nut 64 is then tightened up to secure the driving shaft 18in plane in the sleeve 17 and bearing. rlhe driving shaft Sleeve,securing member 60 is then moved alongthe sleeve 63vand1up to the memberi 23 and bolted thereto by means of nuts cooperating with the ends ofthe screw bolts 44 which pass through lateral openings in the member60.A Then the spring clamping nut 66 may be secured in place to hold thepacking 62 in place. Y

70 (F ig. 1) represents the main driving shaft eirtending through thesupporting axle structure into the differential gearing casing 71, whichis split longitudinally. The differential gearing comprises bevel gear72 secured to the end of the shaft 70 and meshing With a bevel gear 78secured to one end 74 of 'a housing journaled on roller bearings 75. Theother end 76 of the housing is journaled on roller bearings 77, and anintermediate portion 78 of the housing is rigidly secured to the endportions 74 and 76 by means of bolts 7 9. Journaled in the middleportion 78 of the' housing are tivo Worin Wheels 80 and 81 having Worms82 and 88 respectively meshing therewith and journaled in the centralportion 78 of the rotatable housing. A small Worm Wheel 811 is alsojournaled in the central portion 78 of the housing on a spindle andmeshes with both of `the Worms 82 and 86. The driving shaft 18 passesfreely through a central opening inthe end portion 74 of the housing andis keyed to the Worin Wheel 80 of the diffen ential` 'gearing'. Anotherdriving shaft 18a passes freely through a central opening in the endportion 76 of the housing andis keyedto the Worin Wheel 81 of thedifferential gearing. rlhe shaft 18aN drives the traction Wheel on, theopposite side of the vehicle which in vall substantial respects is hesaine as that on the left hand side of Fig. 1 as is previouslydescribed.

Upon driving the shaft 70 the pinion 72 drives 'the bevel pinion 78which, being secured to the housing, rotates the differential housing onthe `bearings 75 and 77. 'This gives the Worm `Wheel 8da planetarymovement which through the Worms 82 and 83 and the Worin Wheels 80 and81 propels the driving shafts. The connection between the vvorni 82 and88 through the Worm Wheel 8l permits of the required differential movenient. This differential movement is "Well known as an"l` and S lackingdifferential, and it is shown and described in United States LettersPatent No. 1,090,082, granted to l/Vm. F. Muehl, March 10, 1914. HOW-ever, any other suitable or Well-known form of differential movement maybe used.`

lf at any time it becomes necessary to remove the differential gearing,the clamp 66 and member 60 (Fig. 2) are loosened so as removed` endivisesufficiently to unkey and free it from the differential gearing Withoutremoving the tread Wheehj and leaving the relatively fixed parta-i. e,pinion 16, sleeve 17 and bearing ring20 supported inplace Within theWheel gearchamber Withouty getting the pinion 16 out of mesh `With thegear 15. fVVith the jack shafts'lthus `displaced, the di'erentialgearing may be taken out by removing the rear half 71 of .the`

casing,- the casing being split `or vdivided along its longitudinalaxis, and suitably bolted together, as is Well understoody and thereforenot shown. y

Since the differential gearing is supported in the casing assembledentirely independent of the jack shafts 18 and 18a, it will remainv inplace after the jack shafts have been removed, and likewise it canbeassembled in place, after repairs, before `the jack shafts arereinserted. Also, since sleevei17 `and pinion 16 at the end of thejackshafts are held supported in place in `mesh Withthe ring gear, thepinion Will remain in posi-1 tion in mesh with the ringl gear after thejack shaft is withdrawn, partlyor Wholly, so there is no danger ofdisplacing or disaranging any of the gearing bythe removal of the jackshafts; and whenV the repairs have been made, either or both jackshafts` for this reason can'y be vvery quickly slipped Vback in placeand the keys in the end of the shaft made toy register With-thekeyivays'in the differential gears byturning'the shaft to bring anysuitable markingsinto register,

such for example as registering lines on the outer ends of the'shaftsand onthe outer ends of the pinions 16, as Will `be Well understood. Byproviding the above arrange= of removing the traction Wheels, the differential gearing is easily removed Without rev quiring any specialapparatus especially for i scribed pertainig especially to the ararnge-'ment for inclosing` the internal gear 15V and pinion 16 and inclosingthe Vbrake apparatus are not herein claimed but they form the `mentpermitting` easy removal ofthe drivf ing shafts 18 and 18a Without thenecessity 120` subject matter of a cofpending application Serial` Number235,085, filed by me on May 17, 1918, entitledV Motor vehicle drivingmechanism. f Y
